SPECIFICATION forming part of Letters Patent No. 346,998,6lated August 10, 1886.

Application filed January 11, 1886. SerialNohlBSflSl. (No model.)

To all whmn it mciy concern.-

Be it known that I, DANIEL KAUFMAN, a citizen of the United States of America, residing at Boiling Springs, in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Metallic Railway-Tracks, of which the following is a specification, reference being had therein to the accompanying drawings.

Figurel is a plan View of my improved metallic railway-track and road-bed. Fig. 2 is a cross-section of the same.

The same letters refer to like of the figures.

My invention has reference to an improvement in the construction of railway-tracks and roadbeds and the preservation of thelatter from the action of the elements and growth of vegetation between and around the crossties, and by keeping the road-bed dry rendering it less likely to freeze and thaw, thereby securing greater safety to passing trains and uniform elasticity, and also greater durability. I also dispense with the ordinary method of ballasting and supply a better ballast than stone or any material now in use. The manner in which I attain these desirable conditions is as follows:

In Fig. 1, A represents a metallic covering over the center portion of the track, extending between the metallic longitudinal sills B and coveriugthe intervening space. The metallic longitudinal sills B have ribs 9 and 9 upon their upper surface at equal distance from the centerof the sill and far enough apart to snugly admit the bottom of the rail R between them. On the inner edge of the sill there is a fiange,f, suitably turned up to form a rest for and support of the outer edges of the metallic covering A, which are turned down over the flanges fand held rigidly in place by annealed wire fastenings w. Upon the outer edge of the sill B there is riveted a longitudinal metallic outer strip, 0, of lighter weight than the sill and extending the entire length thereof, in such position that the outer edge of the rib gwill fall above the inner edge of the metallic strip 0. This strip should extend outward beyond the sill B far enough to assistin holding the track in place, and to form a base adapted in width to the condition of parts in each the ground upon which the road is built. The metallic covering A is laid in sections with a movable water-tight joint, j. distances there is placed a metallic cross-tie,

At convenient T, as shown in the cross-section, Fig. 2, having of the rails, while the bolt 8 and nut n rigidly fasten together the cleat h, the sillB, and crosstie T on the inner side of the rail,the two cleats h and h, with the ribs 9 and g, rigidly grasping and holding the rail, the rails, sills, cross ties, covering, and outer strip being thus securely fastened together when in position for use. The outer strip, 0, has depressions at d to receive the end of the crosstie T. The ends of the sills B are placed far enough apart to afford a space for drainage purposes, as shown in Fig. 1 at the point marked 1, the ends of the rails extending over the ends of the sills and closely approaching each other.

In constructing a railway after the grading has been completed a heavy roller should be passed over the earth. The cross-ties Tshould then be embedded in the ground about even with the surface. The sills B should then be laid flat on the surface of the ground, the outer edge resting agai ust the shoulderp. The outer metallic strip, 0, should then be riveted to the sill B and the bolts 8 and s placed in position. The earth should then be well tamped between the flanges ff. The rails should then be put in place between the ribs 9 and g and the cleats h and h fastened in place in the manner hereinbefore described. Lastly, the covering A should be laid and fastened to the flanges by the annealed wire w.

Having thus fully described my invention, I claim 1. In the construction of a metallic railwaytrack and road-bed, the metallic covering A, in combination with the metallic sill B, having on itsinner edge the flangef, substantially as described.

2. In the construction of 'amctallic railwaytrack and road-bed, the metallic covering A,

in combination with the annealed wire fastenwww l w miwmti 6. The crosstie T, in combination with the outer strip, 0, the sill B, the cleats h and h, the bolts 8 and s, the nuts n and n, the covering A, and annealed wire fastenings w, all in the manner and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.

DANIEL KAUFMAN.
